In those Yahoo rotos, 21-man rosters, I try to use a 5/5 or 6/4 SP/RP split so I don't think you have too many. I also wouldn't be too worried to be projected +37 this early in the season. There will be matchups coming up that you won't be comfortable with and you will want to bench a SP.

Maine has a good swing for a pitcher but on anything that moves, he has no chance. And if it's a fastball, it has to be up in the zone. Basically, the pitcher has to hit his bat. - Mike Pelfrey
